Our testing meets the standards for the Safe Drinking Water Act and is available for testing of rainwater for private use.
Tank water systems provide very palatable water, but are particularly vulnerable to faecal pollution. Birds and other small animals, such as possums leave their droppings on roofs and in gutters which wash directly into the tank whenever there is a reasonable storm.
Roofs, gutters and tanks are often inadequately maintained and cleaned and neglect compromises the quality of the water collected.
When tanks are tested for contamination, they often fail standard faecal pollution tests. In urban areas the presence of airborne contaminants (for example, lead from exhaust emissions) may make collected rainwater unsuitable for drinking.
Because of the low buffering capacity of rainwater, we do see elevated levels of copper and lead in rainwater that is distributed to the house via copper pipes. The following link provides information on Rainwater Plumbing.
Please refer to the Safe Drinking Water Guidelines Information Sheet for further information.
The information pack below contains important information for you to consider before you decide to test your rain water. If you decide to proceed with having your rain water tested please complete the application form included with the information pack.
Publications produced by the South Australian Department of Health provide guidance on the use of rainwater tanks and are available on SA Health website.
